An incremental send operation can miss a truncate operation when an inode
has an increased size in the send snapshot and a prealloc extent beyond
its size.
Consider the following scenario where a necessary truncate operation is
missing in the incremental send stream:
1) In the parent snapshot an inode has a size of 1282957 bytes and it has
no prealloc extents beyond its size;
2) In the the send snapshot it has a size of 5738496 bytes and has a new
extent at offsets 1884160 (length of 106496 bytes) and a prealloc
extent beyond eof at offset 6729728 (and a length of 339968 bytes);
3) When processing the prealloc extent, at offset 6729728, we end up at
send.c:send_write_or_clone() and set the @len variable to a value of
18446744073708560384 because @offset plus the original @len value is
larger then the inode's size (6729728 + 339968 > 5738496). We then
call send_extent_data(), with that @offset and @len, which in turn
calls send_write(), and then the later calls fill_read_buf(). Because
the offset passed to fill_read_buf() is greater then inode's i_size,
this function returns 0 immediately, which makes send_write() and
send_extent_data() do nothing and return immediately as well. When
we get back to send.c:send_write_or_clone() we adjust the value
of sctx->cur_inode_next_write_offset to @offset plus @len, which
corresponds to 6729728 + 18446744073708560384 = 5738496, which is
precisely the the size of the inode in the send snapshot;
4) Later when at send.c:finish_inode_if_needed() we determine that
we don't need to issue a truncate operation because the value of
sctx->cur_inode_next_write_offset corresponds to the inode's new
size, 5738496 bytes. This is wrong because the last write operation
that was issued started at offset 1884160 with a length of 106496
bytes, so the correct value for sctx->cur_inode_next_write_offset
should be 1990656 (1884160 + 106496), so that a truncate operation
with a value of 5738496 bytes would have been sent to insert a
trailing hole at the destination.
So fix the issue by making send.c:send_write_or_clone() not attempt
to send write or clone operations for extents that start beyond the
inode's size, since such attempts do nothing but waste time by
calling helper functions and allocating path structures, and send
currently has no fallocate command in order to create prealloc extents
at the destination (either beyond a file's eof or not).
The issue was found running the test btrfs/007 from fstests using a seed
value of 1524346151 for fsstress.

In preivous patch:
Btrfs: kill trans in run_delalloc_nocow and btrfs_cross_ref_exist
We avoid starting btrfs transaction and get this information from
fs_info->running_transaction directly.
When accessing running_transaction in check_delayed_ref, there's a
chance that current transaction will be freed by commit transaction
after the NULL pointer check of running_transaction is passed.
After looking all the other places using fs_info->running_transaction,
they are either protected by trans_lock or holding the transactions.
Fix this by using trans_lock and increasing the use_count.

dm644x_init_devices() is unnecessarily implemented as a
postcore_initcall().
This does not cause any issues now, but creates issues when
converting to common clock framework where clocks themselves
become platform devices and are initialized later. Because of
this, device clock acquisition and runtime PM on that device
fails.
Move the call to .init_machine() callback along with rest of
platform device's registration.
While at it, convert it to return void since return value is
ignored by caller anyway.

We have the 'ti,davinci-chipselect' property in the device tree, but
when using platform data the driver silently uses the id field of
struct platform_device as the chipselect. This is confusing and we
almost broke the nand support again recently after converting the
platform to common clock framework (which changed the device id in the
clock lookup - the problem is gone now that we no longer acquire the
clock in the nand driver.
This patch adds a new field - core_chipsel - to the platform_data.
Subsequent patches will convert the platforms to using this new field.

If we get an invalid device configuration from a palm 3 type device, we
might incorrectly parse things, and we have the potential to crash in
"interesting" ways.
Fix this up by verifying the size of the configuration passed to us by
the device, and only if it is correct, will we handle it.
Note that this also fixes an information leak of slab data.

Since snd_pcm_ioctl_xfern_compat() has no PCM state check, it may go
further and hit the sanity check pcm_sanity_check() when the ioctl is
called right after open. It may eventually spew a kernel warning, as
triggered by syzbot, depending on kconfig.
The lack of PCM state check there was just an oversight. Although
it's no real crash, the spurious kernel warning is annoying, so let's
add the proper check.

Firmware requires that the ttl value for an encapsulating ipv4 tunnel
header be included as an action field. Prior to the support of Geneve
tunnel encap (when ttl set was removed completely), ttl value was
extracted from the tunnel key. However, tests have shown that this can
still produce a ttl of 0.
Fix the issue by setting the namespace default value for each new tunnel.
Follow up patch for net-next will do a full route lookup.

It is reported that in some cases, write_space may be called in
do_tcp_sendpages, such that we recursively invoke do_tcp_sendpages again:
[ 660.468802] ? do_tcp_sendpages+0x8d/0x580
[ 660.468826] ? tls_push_sg+0x74/0x130 [tls]

[ 660.468880] ? tls_write_space+0x6a/0x80 [tls]
...
tls_push_sg already does a loop over all sending sg's, so ignore
any tls_write_space notifications until we are done sending.
We then have to call the previous write_space to wake up
poll() waiters after we are done with the send loop.

Commit af503716ac14 ("i2c: core: report OF style module alias for devices
registered via OF") fixed how the I2C core reports the module alias when
devices are registered via OF.
But the atmel_mxt_ts driver only has an "atmel,maxtouch" compatible in its
OF device ID table, so if a Device Tree is using a different one, autoload
won't be working for the module (the matching works because the I2C device
ID table is used as a fallback).
So add compatible strings for each of the entries in the I2C device table.

The automatic update mechanism will trigger an update if the
info block CRCs are different between maxtouch configuration
file (maxtouch.cfg) and chip.
The driver compared the CRCs without retrieving the chip CRC,
resulting always in a failure and firmware flashing action
triggered. Fix this issue by retrieving the chip info block
CRC before the check.
Note that this solution has the benefit that by reading the
information block and the object table into a contiguous region
of memory, we can verify the checksum at probe time. This means
we make sure that we are indeed talking to a chip that supports
object protocol correctly.

In ethtool_get_rxnfc(), the object "info" is firstly copied from
user-space. If the FLOW_RSS flag is set in the member field flow_type of
"info" (and cmd is ETHTOOL_GRXFH), info needs to be copied again from
user-space because FLOW_RSS is newer and has new definition, as mentioned
in the comment. However, given that the user data resides in user-space, a
malicious user can race to change the data after the first copy. By doing
so, the user can inject inconsistent data. For example, in the second
copy, the FLOW_RSS flag could be cleared in the field flow_type of "info".
In the following execution, "info" will be used in the function
ops->get_rxnfc(). Such inconsistent data can potentially lead to unexpected
information leakage since ops->get_rxnfc() will prepare various types of
data according to flow_type, and the prepared data will be eventually
copied to user-space. This inconsistent data may also cause undefined
behaviors based on how ops->get_rxnfc() is implemented.
This patch simply re-verifies the flow_type field of "info" after the
second copy. If the value is not as expected, an error code will be
returned.

The ro_release_mr methods check whether mr->mr_list is empty.
Therefore, be sure to always use list_del_init when removing an MR
linked into a list using that field. Otherwise, when recovering from
transport failures or device removal, list corruption can result, or
MRs can get mapped or unmapped an odd number of times, resulting in
IOMMU-related failures.
In general this fix is appropriate back to v4.8. However, code
changes since then make it impossible to apply this patch directly
to stable kernels. The fix would have to be applied by hand or
reworked for kernels earlier than v4.16.
Backport guidance -- there are several cases:
- When creating an MR, initialize mr_list so that using list_empty
on an as-yet-unused MR is safe.
- When an MR is being handled by the remote invalidation path,
ensure that mr_list is reinitialized when it is removed from
rl_registered.
- When an MR is being handled by rpcrdma_destroy_mrs, it is removed
from mr_all, but it may still be on an rl_registered list. In
that case, the MR needs to be removed from that list before being
released.
- Other cases are covered by using list_del_init in rpcrdma_mr_pop.

Pull xfs fixes from Darrick Wong:
"Here are a few more bug fixes for xfs for 4.17-rc4. Most of them are
fixes for bad behavior.
This series has been run through a full xfstests run during LSF and
through a quick xfstests run against this morning's master, with no
major failures reported.
Summary:
- Enhance inode fork verifiers to prevent loading of corrupted
metadata.
- Fix a crash when we try to convert extents format inodes to btree
format, we run out of space, but forget to revert the in-core state
changes.
- Fix file size checks when doing INSERT_RANGE that could cause files
to end up negative size if there previously was an extent mapped at
s_maxbytes.
- Fix a bug when doing a remove-then-add ATTR_REPLACE xattr update
where we forget to clear ATTR_REPLACE after the remove, which
causes the attr to be lost and the fs to shut down due to (what it
thinks is) inconsistent in-core state"
* tag 'xfs-4.17-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
xfs: don't fail when converting shortform attr to long form during ATTR_REPLACE
xfs: prevent creating negative-sized file via INSERT_RANGE
xfs: set format back to extents if xfs_bmap_extents_to_btree
xfs: enhance dinode verifier

We want to work towards phasing out the at24_platform_data structure.
There are few users and its contents can be represented using generic
device properties. Using device properties only will allow us to
significantly simplify the at24 configuration code.
Remove the at24_platform_data structure and replace it with an array
of property entries. Drop the byte_len/size property, as the model name
already implies the EEPROM's size.

Let's show module info if DEBUG is enabled to make it easier to follow
what happens on the suspend and resume path.

Looks like these two device drivers don't yet behave properly for suspend
unless configured with the legacy option.

Starting with omap4, UARTs have different revision register that we need to
detect to enable SYSC_QUIRK_LEGACY_IDLE. Otherwise UARTs won't idle properly.

Starting with omap4 some timers have different sysc registers (type2) compared
to the omap2 timers (type1). We need to detect these to enable the quirk for
SYSC_QUIRK_LEGACY_IDLE, otherwise these won't be idling properly.

Some modules need to use external resets in the rstctrl bits. Typically
only one of the rstctrl bits is for the interconnect target module while
the others are for various child devices.
For ti-sysc driver, we just need the module rstctrl bit mapped. The rest
of the rstctrl bits can be directly mapped to the child devices.

Based on testing with more devices I noticed that some devices
don't suspend or resume properly. We need to PM runtime suspend
and resume devices if we have ddata->needs_resume set.
Let's also improve the error handling and add few debug statements
to make it easier to notice suspend and resume related issues if
DEBUG is set.

Modules that provide resources for other modules need to be suspended
and resumed in the noirq calls. Tag the resource providing modules.
